The international success of “Black Panther” haschallenged the myththat films with predominantly black casts don’t sell ― and it helps unravel “unwritten Hollywood rules,” Jeff Bock, a senior analyst at entertainment research firm Exhibitor Relations, told The New York Times.

“I think about it like a wall crumbling,” Bock said. “In terms of ‘Black Panther,’ no studio can say again, ’Oh, black movies don’t travel, overseas interest will be minimal.’”

Stars of the film, including Chadwick Boseman, Lupita Nyong’o and Danai Gurira, have spoken out about the importance of representation in the movie. “Black Panther,” which is set in the fictional country of Wakanda, shows the possibilities of an African society untouched by colonialism and gender inequity.
